On Thursday evening, a Facebook bug accidentally exposed the people who are posting on climate crisis spokesperson Greta Thunberg’s Facebook page: her dad Svantes Thunberg, and a climate crisis activist located in India named Adarsh Prathap.

Wired Magazine reported the glitch which “allowed anyone to easily reveal which accounts posted to Facebook Pages—including celebrities and politicians—for several hours.”

According to Wired, “All it took to exploit the bug was opening a target page and checking the edit history of a post. Facebook mistakenly displayed the account or accounts that made edits to each post, rather than just the edits themselves.”

The Swedish teen still claims that she wrote everything on her Facebook page, and then Prathap or her dad posted it for her.

After screenshots appeared on Imgur, 4chan, and social media revealing her dad and Prathap’s Facebook accounts were posting for Greta, the Swedish teen (or her dad or Prathap) posted an explanation:

“Some people have been asking who manages this page. First of all, since last spring I only use Facebook to repost what I write on my Twitter and Instagram accounts. Since I have chosen not to be on Facebook personally ( I tried early on but decided it wasn’t for me) I use my father Svantes account to repost content, because you need an account to moderate a Facebook page. The rest that is shared on Facebook is reposted from Twitter and Instagram by the guy who founded the Greta Thunberg Facebook page long before I knew it existed. His name is Adarsh Prathap and he lives in India. Since a lot of people thought it was my official page in the beginning I asked if I could co-manage it and he said yes. All texts posted on my Facebook page has of course been written by me, just like everything else.”

Facebook’s statement about the glitch read: “We quickly fixed an issue where someone could see who edited or published a post on behalf of a Page when looking at its edit history. We are grateful to the security researcher who alerted us to this issue.”
